Munrow's drummer is doing what James Blades says is the basic exercise you need to do to get started playing mediaeval percussion - crotchet-quaver-quaver, no variation, fixed tempo, keep it going for at least half an hour straight. But I think even Blades would have agreed you oughta go somewhere beyond that in performance, and that tune isn't even in a simple modal rhythm.

I didn't like Eclipse's darbuka very much. It wasn't even used in much of the Middle East at the period this music was written - a frame drum (with or without jingles) would have been better.
